I would like to see that graph for the eastern US. The 80's would stand out as incredibly cold, but not in CA. I wonder if a permanent pattern is setting up with these huge stationary high pressure systems over the west, and almost perpetual lows over the east at the 500mb level. This pattern has been going on for a year now.

Might be breaking down for a bit. This winter doesn't seem like the previous one
No. It's been below normal. You're using a graphic based on rankings again... or could be November drove us down more.
Yes, I often use rankings on purpose. Rankings control for the fact some places are naturally more variable than others. 5°F from normal in California is much more unusual than the same departure in the Midwest.
But if you look at the national ranking map, we've been above normal. 82 out of 120, by January to October.

Here's the U.S actual departures from normal for the year. Most is below to near normal. I really hate how they use -2 to 0 as a color. They should have -1 / +1 separated. But obviously NOT above normal.
The difference is the normal used. Your map compares against some 30 year period of record, probably 1981-2010. The ranking map compares against the last 120 years. So it's been been below average compared to the last 30 years, but above average against the last 120 years. Not that far from average for either, though

I kinda call that cherry picking? Whats the purpose mentioning normals then? If that's the case then stop looking at the 30yr normals. Lets go by what you always compare temps too. Next time you post the monthly/yearly mean temp for a location I might ask you what the 120 yr mean is instead. lol

Yes, usually the normals are used. But your cold records are against the period of record, not just 30 years. The graphs posted on the previous page all had much more than 30 years.

Understand but you weren't replying to me. You replied to Tom regarding 2014 maybe being one of the coldest years in a while, but then you showed the 120 yr ranking maps and said it was above normal.
Almost contradicting. Is 2014 one of the coldest years since 1980s? Or are we below/above "normal" (30yr).
So I have 1 question... why did TWC decide to bold these words?
So, just to recap from that TWC article..
Temperatures were below average across most of the country east of the Rockies for the first 11 months of this year.
Temperatures were farthest below average in a swath encompassing the entire Mississippi River Valley and much of the Great Lakes, running 2 to 4 degrees below normal, according to the High Plains Regional Climate Center
So far, it’s been the eighth-coldest year on record in Illinois
Missouri, Iowa, Indiana and Arkansas are having one of their 12 coldest years of the past 120.
There have been 47,402 record lows in the lower 48 so far this year, as opposed to only 33,013 record highs
For just the month of November, there were more than four times as many record lows (8,977) as record highs (2,022).
All this cold weather, and yet the headline for the article talked about a “December Thaw” and they bolded the warm text.
If this isn't transparent to the games out there, I have a number you can call.

The ranking maps were the first thing I found. I can't find a year by year numbers to answer Tom's specific question. My guess is there's been a few years as cold in the last decade or two. Limit to east of the Rockies, and the answer would be diffrente.
